Tip or Ring of one pair is split with the Tip or Ring of another pair
✓
Locating ground faults are more difficult due to multiple ground signal return paths. It is
recommended to locate shorts or crosses whenever possible. Otherwise it may be helpful to
remove shield ground at the transmitter location, then connect the transmitter leads to the
faulted wire and shield.
✓
The cable length beyond the fault should be as short as possible.
